LOCK.

To all whom it may concern Be it known that I, CHARLES E. JOHNSON, acitizen of the United States, and a resident of New Britain, in thecounty of Hartford and State of Connecticut, have invented a new andImproved Look, of which the following is a specification.

My invention relates to the class of devices above mentioned, and anobject of my invention, among others, is to provide a lock in which thebolt can not be moved by force applied at its ends.

One form of lock embodying my invention and in the construction and useof which the object's herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which- Figure1 is a perspective view of a lock embodying my invention. Fig. 2 is aview of the lock case with the back plate removed, parts being brokenaway to show construction, and the bolt being thrown. Fig. 3 is a likeview showing the bolt partially moved and the key being shown and out incross section. Fig. 4 is a View similar to Fig. 2, but with the bolt inits rearward position.

In the accompanying drawings the numeral 5 indicates the back plate and6 the case of my improved look. A bolt 8 having an actuating leg 9 and alocking leg 10 is 'slidably mounted in the case to be actuated by thebit 11 of a key 12 that engages a notch 13 in the leg 9.

The bolt 8 is positively held against endwise sliding movement in eitherdirection so that it can not be moved until released by the key, in theconstruction herein shown by a lug 14 engaging within openings 15 in thewall of the lock case, and this lug being preferably formed at the endof the leg 10. A spring pressing against the leg 9 forces the lug 14into the openings 15 when, in the sliding movement of the bolt, the lugreaches said openings.

In operation the bit 11 of the key moves against one of the releasingsides 1 of the notch 13, shifting the rear end of the lockingSpecification of Letters Patent.

bolt and disengaging the lug 14 from one of the openings 15, as shown inFig. 3 of the drawings. The rotation of the key slides the bolt untilthe lug 14 arrives opposite the other opening 15 when the spring 16shifts the bolt laterally and forces the lug 14 into the other opening15.

While I have shown and described herein a satisfactory form of mechanismfor accomplishing my purpose, this may be departed from to a greater orlesser degree and yet be within the spirit and intent of the invention.

I claim- 1. A case, a bolt movably mounted in the case and havingbranching legs, said bolt projecting through an opening in the case andbeing held against lateral movement therein, holding means carried byone of said legs to lock it against endwise movement, means to engagesaid holding means to cotiperate in the locking operation, means uponthe other leg to receive a key for actuation of the bolt, and means toforce said locking parts into engagement.

2. A case, a bolt movably mounted in the case and having branching legs,said bolt projecting through an opening in the case and being heldagainst lateral movement therein, means carried by one of said legs tolock it against endwise movement, means to engage said holding means tocooperate in the locking operation, means carried by the other leg toreceive a key to move the bolt laterally to disengage said lockingmeans, and means similarly carried to move the bolt longitudinally.

3. A case, a bolt movable laterally and longitudinally within the case,legs branch ing from the bolt, means acting against one of said legs toforce the bolt laterally in one direction, means upon the other leg tolock the bolt against endwise movement in either direction, and means toengage said holding means to cooperate in the locking operation.

4. A case, a bolt slidable within the case, legs branching from thebolt, one of said legs having on its inner edge a surface to be engagedby a key to move the bolt laterally the case and the first rnentionedleg to force and another surface to be engaged by a key said 111g intoengagement with said opening.
